- KonferenzbeitragAus Groß mach Klein: Verarbeitung orchestrierter OGC Web Services mit RichWPS Server- und Client-Komponenten(Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Wössner, Roman; Abecker, Andreas; Bensmann, Felix; Alcacer-Labrador, Dorian; Roosmann, RainerRichWPS is a project aiming at more powerful and more user-friendly support for using the OGC Web Processing Services standard (WPS) for distributed geodata processing in the Web. While we have already discussed in other publications the RichWPS ModelBuilder for geoprocessing-workflow composition as well as the RichWPS approach to geoprocessing-workflow orchestration, this paper sketches the RichWPS Server software as well as some client-side developments facilitating the effective usage of WPS processes.
- KonferenzbeitragAus Klein mach Groß: Komposition von OGC Web Services mit dem RichWPS ModelBuilder(Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Bensmann, Felix; Roosmann, Rainer; Kohlus, JörnDistributed geospatial data and services can be used to form Spatial Data Infra-structures (SDI). Current technological developments enable SDI to process large amounts of geospatial data. In this context, Web Processing Services (WPS) can be used as an open interface standard for accessing and executing geospatial processes. Since many SDI are based on Service-Oriented Architectures (SOA), the orchestration of services is enabled by composing existing services. The results are higher services, e.g. complex geospatial applications. The RichWPS research project focuses on analysing and providing practical approaches of web service orchestration. For this, software components are developed to build a modular orchestration environment. The main client-side application is the ModelBuilder.
- KonferenzbeitragCloud Computing für die Kalibrierung von Hochwassersimulationen(Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Brettschneider, Marco; Pfützner, Bernd; Fuchs-Kittowski, FrankWell calibrated rainfall runoff models of sufficient complexity are a necessary basis for accurate flood water simulations in order to prevent losses. Using the hydrologic modeling system ArcEGMO in a small catchment as an example, IaaS cloud computing has be proven fast and cost-efficient for short-term usage. On the other hand, IaaS cloud instances cannot replace local computers, since long-term usage is still expensive and the performance of the offered architectures can slow down a calibration process on the long run. Ultimately, cloud computing has the potential to be a useful extension of local computer capacities if state of the art computer hardware with a fair pricing is offered by IaaS providers.
- KonferenzbeitragEnergieatlas Schleswig-Holstein(Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Hosenfeld, Friedhelm Hosenfeld; Albrecht, MalteThe energy atlas Schleswig-Holstein represents an instrument supporting the state authorities in performing their tasks in order to promote the energy transition. The web application energy atlas makes governmental data about wind turbines and biogas plants available combined with comprehensive evaluation functions including digital maps presenting the energy plants in the context of other thematic layers like land use. The energy atlas is one of the first applications integrated in a special area of a new data center, observing new challenges and options.
- KonferenzbeitragEntwicklung eines prototypischen Client-/Serversystems zur mobilen Datenerfassung von VOC-haltigen Materialströmen in Automobillackieranlagen am Beispiel der Volkswagen AG(Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Banna, Ahmad; Wohlgemuth, Volker; Witte, Steffen; Meininghaus, RomanAutomotive paint systems include very environmental relevant processes and are complex systems, which complicate the data acquisition for material flow analyses. With the help of a new developed client/server system, VOC including material data can be captured systematically and locally to build a better knowledge of these consumption data for future balances and calculations. The practicality of the developed IT solution was verified.
- KonferenzbeitragErfahrungen mit MongoDB bei der Verwaltung meteorologischer Massendaten(Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Lutz, RichardThe remote sensing of atmospheric trace gases investigates dynamic, microphysical and chemical processes in the Earth?s atmosphere, with the goal to understand, quantify and predict its natural variability and long-term changes. Accurate measurements of atmospheric trace gases from various observational platforms (ground-based stations, air craft, balloons, satellites) provide the data that are required for the modelling of atmospheric processes. The instrument GLORIA (Gimballed Limb Observer for Radiance Imaging of the Atmosphere), developed by KIT/IMK and FZ Jülich, an Infrared Spectrometer, which measures atmospheric emissions, was engaged in several measurement campaigns on board of HALO (High Altitude and Long Range Research Aircraft) and provided a large amount of data, which has to be managed efficiently for processing and visualisation. This paper describes the system background and the use of MongoDB for the provision of measured and processed mass data.
- KonferenzbeitragFlexible Darstellung von geobezogenen Daten in Webseiten über ein ereignis-orientiertes Karten-Widget(Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Düpmeier, Jan; Düpmeier, Clemens; Schlachter, Thorsten; Schillinger, WolfgangBasing on the Google Maps API a web widget was developed in order to generate various digital maps combining different map layers. This web widget can be integrated within the web portal framework LUPO presenting spatial search results on maps complementing the list of fulltext search results.
- KonferenzbeitragDie Implementierung von Umweltbewertungsverfahren in einer dienstebasierten Umgebung(Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Kohlus, Jörn; Kompter, ElisabethIn the following article the results of the RichWPS project, which was promoted by the Federal Ministry of Education and Research (BMBF), are presented from the perspective of its application to perform mandatory tasks of the environmental reporting. The Marine Strategy Framework Directive (MSFD) explicitly claims the use of INSPIRE (INfrastructure for SPatial InfoRmation in Europe) for the provision and processing of data. INSPIRE is based on a network services architecture. A contribution of RichWPS in terms of the implementation of the MSFD is the transfer of assessment methods consistently in a service architecture and the development of tools for a simple and comfortable orchestration of Web Processing Services (WPS) to handle such complex processes.
- KonferenzbeitragKartenservice Umgebungslärm Schleswig-Holstein(Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Hosenfeld, Friedhelm; Gliesmann, Ludger; Rinker, AndreasThis contribution presents the "mapping service environmental noise Schleswig-Holstein": The main component of this web platform consists of a WebGIS with strategic noise maps ("Noise Atlas"). The system was developed in order to support the demands for the first period of the EC Environmental Noise Directive in 2007. The Noise Atlas was since then enhanced continuously, the additions include among others download options for action plans and integration of evaluation platform Disy Cadenza.
- KonferenzbeitragMobiles Crowdsourcing von Pegeldaten(Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Fuchs-Kittowski, Frank; Pfützner, Bernd; Preuß, Tobias; Fischer, Fabian; Beck, Tilman; Bartusch, SarahWith increasing damage caused by natural disasters like flood events in the last decade, the implementation of effective flood management systems has become an important topic. In this paper the hydrological mobile crowd sourcing system KoPmAn is presented, that uses mobile crowdsourcing to integrate water level data collected by the public in a flood management system. The underlying concepts, the architecture, and the implementation of KoPmAn are presented.
